So I totally suck, I just broke a hard vacuum line that goes from the evaporator service port (part #77739-33010, has the little green cap) and runs to the main vacuum housing next to the upper plenum. The hose is about 9" of hard rubber. I don't have a clue how to find a part # for this hose. Would I just be better off to get a hose from advance auto tomorrow, or will i need the factory line? Not having a good day working on the car .............Thanks for any help, I know it may sound vague....

 

This thing?

You could try getting a generic section of hose I don't usually like them due to not matching the bends in the factory part.

 

That looks like it may be it.... Here's a picture I know it's of a RX330 engine but same idea) It's the line that goes from the green evap to the metal fitting, running right over the top of the air intake (few inches from throttle body) to the main vacuum housing, it's about 9" or so in length with the black nylon net in the middle. I tried to circle it but my computer won't let me save the file without my wife's password.

 

Use this site you can look up parts for any Toyota or Lexus

You're the man brother!!! You were right in the first picture, it's the same hose part #23826.

 

does anyone know what the part is called that's circled and big red arrow on, i inspected and the nipple is broke? is it like a cap or do i have to buy the whole thing?

 

anyone knows ^^?

 

Got a better picture? Can't find it in the diagrams.

BTW plastic parts can be repaired using super glue and baking soda, glue the broken pieces then apply more super glue and sprinkle baking soda into the glue. Do this a few times, then reinforce with epoxy.

 

thanks a lot.

 

back again, can anyone tell me what is part # or name of it, its circled on this pic, for some reason i was checking oil today and noticed some is missing, that's what happens when u loan someone ur car.

 

Until you get a replacement...

Get some Super-Glue Gel, clean your three-way junction real good, run a good blob around the break and “clamp” it between two books.

Or go to Autozone because they have plenty of vacuum junctions. Take your broken one for getting the right nipple diameter configuration.
